Benefits of technology
The present invention relates to a method for controlling multiple machines and devices in an automation cell, particularly industrial robots. The invention provides a way to improve the control of multiple machines in a heterogeneous installation with different types of controllers and machines. The invention involves the distribution of programs to controllers of each machine in a multiple-machine arrangement in a compressed data form, with unambiguous identification features of the target system. The data packages are transferred to the controllers in parallel, for example via a network or a central planning device. The activation of the target systems or their controllers can be done selectively, and the installation of data packages can be initiated in a preparation phase before the installation phase. The invention allows for the efficient control of multiple machines and devices in an automation cell.
Problems solved by technology
This makes it difficult to implement new projects in such heterogeneous automation cells, which projects in particular require different programs and configuration data for the different controllers.
The controller of heterogeneous multiple-machine arrangements does not satisfactorily facilitate this procedure.

Embodiment Construction
FIG. 1 shows an automation cell or multiple-machine arrangement with two six-axis industrial robots 11, 21 and their respective PC-based robot controllers 10 and 20. The industrial robots 11, 21 insert tools (not shown) into a press 31 with an SPS 30, or remove tools from the press 31 and place them on a conveyor 41 with an SPS 40.
The robot controllers 10, 20 and the press SPS 30 are directly linked with an Ethernet network 100 (indicated with a dash-dot line in FIG. 1); the conveyor SPS 40 is indirectly linked with said Ethernet network 100 via a proxy 42. A notebook 50 and a backup server 60 in which data (for example state data of the controllers 10, . . . , 40 can be stored) additionally communicate with this network.
In order to now implement a new project (for example the processing of different work pieces) or a new project version (for example with modified, optimized workflows) in this heterogeneous automation cell, in a first step S10 (see FIG. 2) the planning device 50 gen...

In a method and device to control a multiple-machine arrangement with at least one first controller and one second controller, specific data packages for the controllers are generated, these specific data packages are transferred to the controllers, the transferred data packages are selectively activated, and downloading of the data packages is implemented in the controllers as a result of an activation, in particular installation of at least one program and / or one configuration file.
Description
BACKGROUND OF THE INVENTION1. Field of the InventionThe present invention concerns a method and a device for controlling a multiple-machine arrangement with multiple controllers, in particular an automation cell with two or more industrial robots.2. Description of the Prior ArtIn automation cells—for example production cells such as welding, enameling or installation cells—very dissimilar machines—for example robots, tool machines, conveyors and the like—are frequently used by different manufacturers, and even machines of the same type can still differ, for example by the type and / or the version of their controller.This makes it difficult to implement new projects in such heterogeneous automation cells, which projects in particular require different programs and configuration data for the different controllers.A control system, method and computer program are known from EP 1 738 235 B1, in which a robot controller sends information to a human-machine interface so that the correct ve...
